Revelation 2:3,4 says:
"To the angel of the church of Ephesus write,
`These things says He who holds the seven stars in His right hand, who walks in the midst of the seven golden lampstands: "I know your works, your labor, your patience, and that you cannot bear those who are evil. And you have tested those who say they are apostles and are not, and have found them liars; and you have perseverance and have endured for My name's sake, and have not grown weary.
"Nevertheless I have this against you, that you have left your first love.
Do you think they forsake their first love because they got caught up in the works, or was it for another reason?
